At the 2013 Cannes Film Festival, Longoria picked up her dress to keep from tripping as she ascended a staircase -- and showed her lady parts to the photographers. Oops. Maybe "underwear" is the way to go. « Less

A hint of Grace's areola appeared to be peeking out of her dress after a Sept. 26, 2011 "Dancing with the Stars" performance.

At the 2012 Emmy Awards, moments before the "Modern Family" cast took the stage for their Best Comedy Series win, Sofia Vergara had a zipper malfunction. But she was in good spirits about it -- she tweeted the photo herself. « Less

During the 2012 Oscars, JLo's cleavage-enhancing outfit appeared to show more than intended. Her stylist denied such a reveal saying that protective measures were in place. We'll never know for sure. « Less

Squirrel-friend had a nip slip while performing on "Good Morning America" in August. National TV slip!

If the Internet is to be trusted (and I think we all know that it isn't), Pammy here is sort of the Grand Dame of nip slips. There have been repeated public sightings of the twins in news reports, including a runway in 2009 and a New Year's Eve event in 2010. It's never too late to turn over a new leaf, Pam! Repeated nip slip! « Less

Janet "Privacy" "Control" Jackson was the nip slip trailblazer with her 2004 Super Bowl "wardrobe malfunction," which may or may not have been planned in advance. Historical nip slip! « Less

Ms. Ricci looks snappy here, but she was decidedly more casual in 2007, when she broke free from the confines of her clothes, albeit only slightly. Classy nip slip! « Less

This almost feels like a given, but Lindsay Lohan enters our list courtesy of a nip slip at a photo shoot this summer. Along with fellow-nip-slip-victim Paris Hilton, the only surprise would be if she hadn't let one slide. Obvious nip slip! « Less

Oh, Tara. Tara, Tara, Tara. The little lady is all covered up here, but walking the red carpet in 2006, Tara's entire boob came unleashed from her dress. It wasn't so much a "nip slip" as it was "a complete nipple unveiling." But Ms. Reid took one for the team and taught actresses everywhere about the importance of fashion tape. Classic nip slip! « Less

There are nip "slips," in which the accidental nature of said slip is highly dubious, and actual nip slips. Though there really is no guarantee, Ms. Knightley here didn't seem like the "check out my boob!" kind of starlet when her dress crept a bit too low at the "Pride and Prejudice" premiere. Actual nip slip! « Less
